20x^2-25x-1=0
a = 20; b = -25; c = -1;
Δ = b2-4ac
Δ = -252-4·20·(-1)
Δ = 705
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-25)-\sqrt{705}}{2*20}=\frac{25-\sqrt{705}}{40} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-25)+\sqrt{705}}{2*20}=\frac{25+\sqrt{705}}{40} $
